Starbucks has been both lauded and lampooned for enforcing its own names for drink sizes -- the "Tall," "Grande," and "Venti." Now the coffee empire is offering a fourth size: the 31-ounce "Trenta," which will be rolled out across the country over the next few months. The National Post created a helpful diagram that compares the Trenta to the other size offerings at Starbucks and the capacity of the human stomach. Check it out after the jump:

The Trenta is only available for iced beverages, but watch out for what they pack in there: some of Starbucks' cold drinks, like the popular Frappuccino, already tip the scales at 700-plus calories in Venti sizes.
